AGING WORKFORCE: Growing demand for senior services provided by nurses’ aides, home health aides and other such workers along with aging baby boomers has led to more employment for senior caregivers.

FILLING A NEED: Some of the change is driven by the overall aging of the population and the trend of people working later in life. But with high turnover and a constant need for more workers, home care agencies are willing to hire older people new to the field who have found a tough job market as they try to supplement their retirement income.

THE BAD NEWS: The jobs are among the fastest-growing positions in the U.S., but are also notoriously physically demanding, with low pay and high rates of injury.
